Theres often so much things to remember in many subjects and I often rely on mnemonics to remember
For example:
IPT
The informaton processes are
Collecting
Organising
Analysing
Storing & Retrieving
Processing
Transmitting
Displaying
I memorise it with:
Come
On
All
Students
Pat
The
Dog
2U Mathematics
Theres the sine, cosine and tangent ratio ...
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
And we remember SOH CAH TOA
The quadrant ratios in trigonometry is one of the easier ones to remember.
All ratios are positive in 1st quadrant
Sine ratio is positive in 2nd quadrant only
Tangent ratio is positive in 3rd quadrant only
Cosine ratio is positive in 4th quadrant only
OR
1st Quadrant - All ratios
2nd Quadrant - Sine
3rd Quadrant - Tan
4th Quadrant - Cos
The most common mnemonic is:
All
Stations
To
Central
NOTE:
My 3U maths class isnt close enough to the quadrant trigonometry yet ... I want to learn ahead !
Chemistry
We were supposed to learn off by heart to determine if certain ionic compoudns were soluble or insoluble.
The practical task I did recently did little to help, although I did score some good marks of 25/31 ... If I wore safety glasses I would get extra marks .. Lets not get carried away
Now,
How the HELL am I supposed to remember all this ???
Soluble Ionic Compunds
Group 1 and ammonium
nitrates
acetates (ethanoates)
chlorides, bromides and idodides (except silver and lead ions)
sulfates (except silver, lead, barium, strontium, and calcium ions)
Insoluble Ionic Compunds
carbonates, sulfites and phosphates (except group 1 and ammonium compunds)
hydroxides and oxides(except Group 1, ammonium, barium, strontium and calcium ions)
sulfides (except Groups 1, 2 and ammonium ions)
